INCANDESCENT BURNER FOR LIQUID HYDROCARBONSB Specification of Letters Patent.

Application filed January 22, 1907. Serial No. 353,428.

To all whom it may concern.-

Be it known that I, ROBERT EMIL WAL- THER, a subject of the King of Saxony, and a resident of Schulstrasse 5, WVerdau, Kingdom of Saxony, German Empire, have invented a new and useful Improvement in Incandescent Burners for Liquid Hydrocarbons, of which the following is a specification.

This invention relates to improvements in atmospheric burners for liquid combustibles for lighting and heating purposes.

According to my invention the burner is provided with a wick tube head in the form of a hollow open ring of metal preferably metal of small heat conducting capacity, closed and sloped at the top. Fresh air continually entering and passing through the hollow space within the ring takes up the greater part of the heat which is imparted to it by the flame and rapidly conducts it away to the surrounding air so that transmission of the heat to the wick tube is prevented, the combustion of the wick at the Wick tube insured over the entire exposed outside and heating of the wick tube and distortion of the burner prevented. Ahollow ring of this kind can be very easily made in comparison with solid rings made for example from steatite or the like and in comparison therewith is very durable and very cheap while being just as useful and efficient.

Onto the hollow ring is drawn a smooth perforated or a corrugated ring ending with its top edge in the same horizontalplane as the top edge of the said hollow ring and being prevented from slipping off by a projecting flange on the hollow ring and in the corrugations of which are provided air entrance openings, for the purpose of conducting air in definite quantities and in the form of jets to the sloped off or shouldered down upper edge of the hollow ring and thereby insure an always uniform burning of the flame.

On the accompanying drawing Figure 1 is a vertical section of the atmospheric burner, Fig. 2 is a plan view and a partial horizontal section of the atmospheric burner.

a is a hollow open ring of metal closed and sloped at the top, forming the wicktube head. I) is the wick externally surrounded by the wick tube 0, onto which the wick tube head a, is fixed in such a manner that fresh air will continually enter and pass through the hollow space within the ring a. Therefore the latter will rapidly conduct the greater part of the heat which is imparted to it by the flame away to the surrounding air so that a transmission of the heat to the wick tube is prevented, the combustion of the wick at the Wick tube insured over the entire exposed outside and heating of the wick tube and distortion of the burner prevented.

d is a corrugated ring drawn onto the hollow ring a, and e is a projecting flange on the hollow ring, which prevents the corrugated ring d from slipping off. Within the corrugations of the latter are provided air entrance openings f for the purpose of conducting air in definite quantities and in the form of jets to the sloped oif or shouldered down upper edge of the hollow ring and thereby insure an always uniform burning of the flame.

The construction hereinbefore described is simple as it requires but few parts to form an effective and very economic burner.

What I claim is:

1. In an atmospheric burner for liquid combustibles for lighting and heating purposes the combination with a wick, of a wick tube externally surrounding the wick of a hollow open ring of metal closed and sloped at the top and provided on the wick tube thus forming a wick tube head of a second ring drawn onto the hollow ring and ending with its top edge in the same horizontal plane as the top edge of said hollow ring of air entrance openings in said second ring for conducting air in definite quantities to the sloped ofl' upper edge of the hollow ring and of means for preventing the second ring from slipping off the hollow ring, substantially as described and specified.

2. In an atmospheric burner for liquid combustibles for lighting and heating purposes the combination with a wick, of a wick tube externally surrounding the wick of a hollow open ring of metal closed and sloped at the top and provided on the wick tube thus forming a wick tube head, of a corrugated ring drawn onto the hollow ring and ending with its top edge in the same horizontal plane as the top edge of said hollow ring of air entrance openings provided within the corrugations of said ring for conducting air in definite quantities and in the form of jets to the sloped ofl upper edge of the hollow ring, and of a projecting flange provided on the hollow ring and preventing the corrugated ring from slipping ofi the same, substantially 5 as described and specified.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two Witnesses, this tenth day of Jan- Witnesses:
